During Pavlovian conditioning, Sign-Tracker (ST), Goal-Tracker (GT), and Intermediate (IN) phenotypes emerge, as characterized by the degree to which an individual attributes incentive salience to reward-associated cues. These operationally defined phenotypes differ in other respects: In human studies, STs tend to favor bottom-up attention, while GTs tend to favor top-down attention. There is some limited evidence that rats exhibit similar patterns during Pavlovian conditioning.

Adenylosuccinate lyase deficiency (ADSLd) is a rare autosomal recessive purine metabolism disorder with several clinical manifestations. While toxic substrate accumulation is a known hallmark, no additional molecular mechanisms have been established. Here, we show that ADSLd is associated with mitochondrial dysfunction, including increased fragmentation, impaired respiration, and reduced ATP production.

Background: Chronic rejection is a major cause of long-term kidney allograft failure, characterized by persistent inflammation and progressive fibrosis. Macrophages are central mediators of this process, but their phenotypic heterogeneity and regulatory mechanisms in chronic rejection remain incompletely understood.
Methods: We performed single-cell transcriptomic analysis on renal allograft biopsies from patients with different types of rejection and on a time-course rat model of chronic rejection.

Endoxifen is the most active metabolite of tamoxifen and plays a central role in its therapeutic efficacy. However, significant interindividual variability in endoxifen plasma concentrations, driven by both genetic and non-genetic factors, may result in subtherapeutic exposure for a substantial subset of patients. This study evaluated the influence of CYP2D6 phenotype and age on endoxifen steady-state concentrations and explored the clinical utility of therapeutic drug monitoring (TDM) to guide tamoxifen therapy.

Sonic hedgehog (SHH) is a major intercellular signaling pathway involved in the orchestration of embryogenesis, including orofacial morphogenesis. The SHH pathway is sensitive to disruption, including both genetic predisposition and chemical-induced disruption at multiple molecular targets including antagonism of the SHH signal transducer Smoothened (SMO). Here we report the adverse outcome pathway (AOP) 460 describing the linkage between antagonism of the SMO receptor, a key intermediate in the hedgehog signaling, and orofacial clefts (OFCs).
